                         AMENDMENT TO WARRANT AGREEMENT

     THIS AMENDMENT TO WARRANT AGREEMENT (this "Amendment"), dated as of March
28, 2001, is between TRANSTEXAS GAS CORPORATION, a Delaware corporation
(together with its permitted successors and assigns, the "Company"), and
CHASEMELLON SHAREHOLDER SERVICES, L.L.C., a New Jersey limited liability
company, as warrant agent (together with its permitted successors and assigns,
the "Warrant Agent").

     WHEREAS, the Company and the Warrant Agent entered into that certain
Warrant Agreement dated as of March 15, 2000 (the "Warrant Agreement")
(capitalized terms used but not defined herein have the meaning assigned to such
terms in the Warrant Agreement);

     WHEREAS, pursuant to the terms and conditions of the Warrant Agreement,
Warrants to purchase initially up to 625,000 Warrant Shares may be issued;

     WHEREAS, Section 7.15 of the Company's plan of reorganization under Chapter
11 of the United States Bankruptcy Code (the "Plan") requires rounding and
adjusting, as necessary, the total number of Warrants actually issued under the
Warrant Agreement and, as a result of the rounding provided for therein,
Warrants to purchase 504 Warrant Shares in addition to the 625,000 Warrant
Shares specified in the Warrant Agreement were required to be issued;

     WHEREAS, pursuant to, and as contemplated in, the Plan, the Company and
John R. Stanley ("Executive") entered into that certain Employment Agreement
dated as of March 17, 2000 (the "Employment Agreement"), whereby the Company
agreed to issue to Executive each year during the term of the Employment
Agreement Warrants to purchase 37,500 Warrant Shares (a total of up to 112,500
Warrant Shares), pursuant to the Warrant Agreement;

     WHEREAS, the Warrant Agreement inadvertently failed to provide for the
additional number of Warrants to be issued in accordance with the rounding
provision in Section 7.15 of the Plan and the issuance of Warrants to Executive
pursuant to the Employment Agreement as provided for in the Plan;

     WHEREAS, the Company and the Warrant Agent desire to amend the Warrant
Agreement to provide for the issuance of the additional Warrants necessary to
permit the rounding provided for in the Plan and the additional Warrants
issuable pursuant to the Employment Agreement;

     WHEREAS, Section 7.3 of the Warrant Agreement provides that the parties
thereto, without the consent of any Holder, may amend the Warrant Agreement for
the purpose of curing, correcting or supplementing any defective provision
contained therein, provided that the Company determines that the amendment shall
not adversely affect the rights of the Holders; and

     WHEREAS, the Board of Directors of the Company has determined that this
Amendment shall not adversely affect the rights of the Holders.
